Faith as Trust in Jesus Christ in Christian Theology

Faith, in a broad sense, is the mind's persuasion that a statement is true [3]. This general understanding of faith implies that something is true and therefore worthy of trust [3]. In a more specific sense, particularly within a Christian framework, faith is often understood as trust in Jesus Christ. This trust is not merely an intellectual assent but a dynamic, working reality that manifests in actions and attitudes [12].

The concept of faith as trust is deeply embedded in biblical language. The Greek word pistis, often translated as "faith," also carries the meaning of "assurance" or "pledge" [4]. For instance, 2 Corinthians 3:4 states, "And such trust we have through Christ toward God" (Webster) [1], or "And such trust have we through Christ to God-ward" (KJV) [2]. This highlights a direct connection between trust and Christ as the mediator of that trust towards God.

Elements of Faith

Faith is not a blind leap but is intrinsically linked to knowledge and understanding. Easton's Bible Dictionary notes that knowledge is an essential element of faith and is sometimes used interchangeably with it, as seen in John 10:38 and 1 John 2:3 [3]. However, faith distinguishes itself from mere knowledge by including assent, which is an active engagement of the mind [3]. This implies that faith involves not only knowing about something but also agreeing to its truth and committing to it.

Faith also admits of varying degrees, ranging up to "full assurance of faith" [3]. This "full assurance" (Greek plerophoria) signifies a complete fullness of faith in God that leaves no room for doubt [4]. It is an unwavering conviction in the truth of scriptural declarations and a joyful steadfastness in having grasped that truth [4].

Faith, Hope, and Love

Faith is frequently discussed alongside hope and love, forming the three main elements of Christian character (1 Corinthians 13:13) [5]. While distinct, these three virtues are interconnected. Hope, for example, is an essential and fundamental element of Christian life, so much so that it can designate the essence of Christianity itself (1 Peter 3:15; Hebrews 10:23) [5]. Christ is the ultimate object of a believer's hope [5]. Unbelievers are described as being "without this hope" (Ephesians 2:12; 1 Thessalonians 4:13) [5].

The "work of faith" is described as its "working reality," demonstrating alacrity in receiving truth and manifesting itself through its fruits [12]. This is not a passive assent but an active, continuous chain of "work" [12]. This active nature of faith is further emphasized in Galatians 5:6, where faith in Christ Jesus is understood to provide access to God's favor and grace, and is expressed through love towards others [21].

The Object of Faith: Jesus Christ

The focus of this trust is Jesus Christ. The righteousness that is imputed to believers is described as "the righteousness of faith" (Romans 4:13; 9:30; 10:6) and "the righteousness of God by faith in Christ" (Romans 3:22) [8]. Christ is presented as the one who becomes righteousness for believers (1 Corinthians 1:30) [8]. This highlights that faith is not merely a general trust in a divine being, but a specific trust in the person and work of Jesus Christ for salvation and righteousness.

The concept of "faithful" as a designation for Christians means being "full of faith" or "trustful" [7]. This contrasts with merely being trustworthy, emphasizing the internal disposition of reliance on God through Christ [7].

Historical and Theological Perspectives

Throughout Christian history, theologians have elaborated on the nature of faith as trust in Christ. John Calvin, a prominent Reformed theologian, frequently emphasized the importance of faith in his commentaries [9, 10, 14, 17, 19, 20]. While the provided excerpts do not offer a direct definition of faith from Calvin, his extensive scriptural commentaries underscore the centrality of faith in understanding biblical narratives and theological concepts. For instance, his commentaries on Isaiah and Genesis touch upon numerous passages that implicitly or explicitly deal with faith and trust in God's promises and actions [9, 10, 14, 17, 19, 20].

Similarly, Eastern Orthodox theologians like John Chrysostom, in his homilies, also engaged with the concept of faith, often in the context of interpreting New Testament epistles and Old Testament narratives [11, 13, 15, 18]. While the provided excerpts do not offer a direct definition of faith from Chrysostom, his extensive scriptural commentaries demonstrate the pervasive nature of faith as a theme in early Christian thought.

The idea of "righteousness imputed" is a key theological concept linked to faith in Christ [8]. This righteousness is revealed in the Gospel (Romans 1:17) and is considered to be "of the Lord" (Isaiah 54:17) [8]. It is a righteousness that comes "without the law" (Romans 3:21) and through faith in Christ [8]. This understanding underscores that salvation is not achieved through human effort or adherence to legal codes, but through a trusting reliance on Christ's work.

The happiness of believers is linked to their trust in God (Proverbs 16:20; Philippians 4:6-7) [6]. This trust brings peace and is a source of joy and steadfastness [4, 6]. The "work of righteousness" is described as peace, both internal and external [16]. This suggests that faith, as trust in Christ, leads to a state of peace and well-being for the believer.
